      I've already created an issue on Stackoverflow: https://stackoverflow.com/questions/78755214/zk-10-messagebox-show-in-doaftercompose-stops-page-rendering 

       

      I am working on upgrade from ZK 8.5.2.1 to version 10, latest hotfix for jakarta. After fixing multiple complications, I am now stuck with unexpected behaviour of Messagebox.show(). I need user to choose a Messagebox btn and then update some data in DB, based on users choice. In older version, Messagebox showed a modal window and in the meantime, my server code continued processing and pushed content to browser. So behind the Messagebox there was a fully rendered page. Now, in ZK10, Java code continues as well, but browser is not rendering any components in the background of Messagebox.

      Only thing I found in docs is deprecated use of Event thread processing which I am not using. When I disable showing a Messagebox, page is rendered without any troubles.

      What should I do to get back the expected behaviour?

      fragment of Messagebox creation (only difference):

      // ...doAfterCompose() - check if its read or unread and offer user to mark as read
      if (!TrueFalseConverter.instance().nvlFrom(entity.getLPrectena())) {
          Messagebox.show(Labels.getLabel("diaries.make.msg.question.order.set_read.text"), Labels.getLabel("diaries.make.msg.question.order.set_read.title"), Messagebox.YES | Messagebox.NO, Messagebox.QUESTION, new SerializableEventListener<Event>() {
      
              @Override
              public void onEvent(Event event) throws Exception {
                  if (Messagebox.ON_YES.equals(event.getName())) {
                      entity.setLPrectena(TrueFalseConverter.instance().to(Boolean.TRUE));
                      app.r.ovdenObjednavkyRepository.store(entity);
                  }
              }
          });
      }
      // ...continue with components creation and render the page

      Debug Information

      I turned on the TRACE logging.

      With Messagebox, ExtendletLoader loads only 2 WPD files:
